Lets call "real" an appender which will create the one and only array, i.e. it
will not randomly create a copy of array on appending. Such copy is bad as:
1. Almost no use.
In 99% appender is used as "real" appender and the copy is not needed.
2. Performance.
It will cause calls of postblits and then destructors on collection of copy
array.
3. Needless restriction on element type.
One may want to create and array of uncopyable type which non-"real"
appender can't do by definition.
Obviously, "real" appender is uncopyable and don't give safe access to its
array until it finished.
